Tiny home rules in Vista, CA — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Vista permits tiny homes on foundations as ADUs under state ADU law. Tiny homes on wheels (THOWs) are not recognized as permanent dwellings under VMC. Minimum dwelling unit sizes apply per the development code.
Vista allows tiny homes on permanent foundations as accessory dwelling units (ADUs) under California Government Code §65852.2 and VMC Chapter 14. Junior ADUs can be as small as 150 sq ft, and detached ADUs up to 1,200 sq ft. Tiny homes on wheels (THOWs) are classified as recreational vehicles and cannot serve as permanent residences on residential lots; they are subject to RV parking rules. Factory-built tiny homes on foundations must meet HCD standards or CBC requirements. All ADU-classified tiny homes must have kitchen, bathroom, and sleeping facilities. Setbacks for detached units are typically 4 feet from side and rear property lines per state ADU law. No owner-occupancy requirement for either the primary unit or ADU. Contact Community Development (760) 639-6100 for pre-application consultation.
Code Enforcement action for unpermitted dwelling units. Fines for occupying THOWs as permanent residences. Abatement orders possible.
